Those are both absolute crap. Get a real set of tweeters or horns from PartsExpress.

You can't just swap x-overs around like baseball cards into any set of speakers. For a new set of drivers like your doing I suggest seperate HP and LP filters for each driver rather than a unified 2 way x-over. Pick a x-over freq well within the frequency range of both drivers. Probably around 2 KHz. The filters must be chosen to match the impedence of the drivers, and then you may need to add a pad to the horn to match the levels better.

seleniums is the way too go, but those are not tweeters

*Frequency response: 400-9,000 Hz

well wat xover do i need for those seleniums and i am putting them on my flats boat under the polling platform so i can hear music while running full throttle

HP filter at 1000 Hz, LP filter at 1000 Hz. You will probably still need a pad or dial type dampner to adjust down the highs.

well i can just turn the gain down they dont need much to get loud i heard

i've run selenium horns without xovers before, they did fine

 

[brazilianguy 10+ year member]

100w and they will be very very happy

well the amp i am gonna use is a cheap xplod amp only has a lp and a off setting so if i turn it to off then i cant adjust the freq to the seleniums so i need something to prevent low freq's

You use a passive High Pass filter on the horns to block the bass. You use a passive Low Pass filter on the woofer to block the highs. You need a pad on the horn to reduce the power of the horn compared to the woofer or it will sound like a tin can with no bass.

i thought these horns are for only highs vocal range basically i dont want any bass from it period just vocals, i will have mids for midbass and a 12" sub
